Benchmarking in Multimedia and Retrieval related research fields has a long tradition and important position within the community. Benchmarks such as the MediaEval Multimedia Benchmark or CLEF are well established and also served by the community. One major goal of these competitions beside of comparing different methods and approaches is also to create or promote new interesting research directions within multimedia. For example the Medico task at MediaEval with the goal of medical related multimedia analysis. Although lifelogging creates a lot of attention in the community which is shown by several workshops and special session hosted about the topic. Despite of that there exist also some lifelogging related benchmarks. For example the previous edition of the lifelogging task at ImageCLEF. The last years ImageCLEFlifelog task was well received but had some barriers that made it difficult for some researchers to participate (data size, multi modal features, etc.) The ImageCLEFlifelog 2018 tries to overcome these problems and make the task accessible for an even broader audience (eg, pre-extracted features are provided). Furthermore, the task is divided into two subtasks (challenges). The two challenges are lifelog moment retrieval (LMRT) and the Activities of Daily Living understanding (ADLT). All in all seven teams participated with a total number of 41 runs which was an significant increase compared to the previous year.
